Crackling in brain

I hope you are well.

Having read up on your achievements and looking for the best I now turn to you for your help.

Please take time to review the symptoms below and tell me if you know what this could be.

SYMPTOMS

Feels like Electricity in my head, like a crackling fluid, a pile of sand that gradually trickles through.

My head constantly cracks between 50 and 100 times a day, sometimes I jump because the electric like pulse is so strong.

My memory is very poor, I am always tired but fit. I get anxiety and feel dizzy and unbalanced. I find it hard to concentrate on one thing, my head isn't clear it's all over the place. When in conversation with someone I often drift in and out

I was severely attacked at a nightclub approx 3 and a half years ago and had my ear stitched at Southend Hospital. My symptoms have been going on for 1 and a half years but are getting worse.

I have been told at A and E that it is congestion behind the ear, my local GP says there is no congestion.

I have had an MRI Brain scan on 24/12/08, it came back clear. My blood test and urine sample came back clear

I have been taking Ibroprofen, Kalms to help with anxiety and Vioform ear drops which were recommended to help symptoms from the consultant at A and E.

I seem to have recently acquired blurred vision, feel unstable and sick due to dizziness or vertigo. I feel spaced out or unbalanced.

Conditions seem to increase when I am on the phone for long periods of time, this is every day.

I have seen an ENT specialist at the Wellesley Hospital which is a private Hospital in Southend on sea. I spoke to a Mr Warwick Brown who is a senior ENT HEAD SPECIALIST. He said there is nothing wrong with my Ears, nose or throught. For 25 minutes with him it has cost me �160

I have another MRI booked for Wednesday the 29th April 2009. This is for Brain but they will hopefully focus around the IAMS area or behind the ear. This seems to be where my symptoms mainly arise. This would have cost me �680 per scan and I required two scans.
I do appreciate your time in reading through this letter and just hope there is an answer........

Yours sincerely
